gRPC
gRPC is a high-performance, open-source remote procedure call (RPC) framework developed by Google that uses HTTP/2 for transport and Protocol Buffers as its interface definition language. It enables efficient communication between services in distributed systems by providing features like bidirectional streaming, flow control, and authentication. It is widely used in microservices architectures, cloud-native applications, and mobile backends for its speed and language-agnostic design.
Developers should learn and use gRPC when building high-performance, scalable distributed systems, such as microservices or cloud applications, where low-latency communication and efficient serialization are critical. It is particularly valuable in polyglot environments where services are written in different programming languages, as it provides a consistent, type-safe API across languages. Use cases include real-time data streaming, IoT device communication, and inter-service communication in Kubernetes clusters.
